The best description of Ernest Rutherford's experiment is letter C. The positively charged particles were fired through a gold foil. Most of these particles went right through, while others bounced back. This experiment led to the discovery of the nucleus.

Answer : Option C) Positive particles are fired at gold foil. Most pass through, but some bounce back.

Explanation : In Ernest Rutherford's experiment he used a beam of alpha particles which were aimed at very thin gold foil and their passage through the foil was detected. Now, these alpha particles were the positive particles which were fired on the gold foil. Many of the alpha particles were found to pass through the foil but there were some particles which bounced back. This whole model was called as plum pudding model for his study.
